WINDING MECHANISM I Application filed December 6, 1930, Serial No.

This invention refers to 'a motor vehicle pulling apparatus mounted on a detachable tripod which is operated by hand and independent of the motor of the vehicle.

Reference is made to the accompanying drawings in which: 7 I

Figure 1 is a side view of the complete apparatus mounted on a tripod and ready to operate after being coupled to the vehicle.

Figure 2 is a side view of theeasing vcontaining the mechanism but without the operating lever, a detachable cover therefor being shown in section.

Figure 3 is a front view ofthe casing showing th interior mechanism and showing the cover placed in position on its rear part.

Figure 4 is a front view of the operating lever.

, Fi ure 4a is a side view thereof.

Figure 5 is a View of the axle on which the lever rotates and to which are fixed the pike of the front Figure 8 is a view of the detachable supplementary lever on the axle of the drum.

The invention consists of a casing 1, Figures 1, and 2, which is cast in oneblock from any known metal.

The casing'l is provided with two bushings in which are journalled the axles 9 and 19. The axle 9 carries a drum provided with spiral grooves and-gears and which are f V and 4 a, has aj'stem socket 167 provided Wltll' dotted lines in the preferably cast in one block of a. material similar to the material of the casing 1 and resistant to friction and flexion. This drum is fixed to the axle 9 by means of a key.

In the spiral grooves of drum 7 is wound the tractive cable 3, the end of which is provided with a hook to be fastened to the vehicle which is to be hauled out of the mire. The length of this tractive cable 3'depends on the prevailing requirements and it may be provided with coupling rings at convenient intervals in order to reduce or increase the length. v

The casing 1 is formed with downwardly and inclined lugs 27 and 28 having sockets wheel 14 are fixed on the axle 19 b and fits around the axle 19. p In the stem socket 16 the lever 15' is intro- 500,530, and in Ar'gent iiea au ust 2 2, 1930.

therein in which arep ositioned the upper ends of legs 10'and 13 which support the casing. On the axle 19 the double pinion '12 actuates and operates the gear anddrum? and the ratchet wheel 14 which bymeans of the" lever 15 operates the said double pinion 12.

These part's,- the double pinion'12 and ratchet J g y means of wedges placed in the sockets 20. 4

A pawl 24- is piv'otally' mounted onthe casing and spring pressed into engagement with the teeth of the ratchet wheel 14 to g each provided with a concave disc 5 to'act as a support and to limit the penetration of the spike in the ground.

The rear leg v to the legs already described;

'j Onthe axle 9 of the drum 7 the supplementary detachable lever 26 operates in or der to wind the cable more rapidly on the spiral grooves of the said drum 7.' i

In order to disconnect the holding pawl 24-, and allow a back provided.

The lever 15, which is designed to operate it movement given by the person who wishes to haul the vehicleyis co the head-and lever; I V

The head of the lever shown in Figures 4 the cavity 17] as shown in said figuresa j v The hooked shaped device 18 is a duced, which should be constructed of laminatedpiping or otherwise and made of metal similar to that used for 'the casing 1, resist-- ant to the flexion to which it is submitted.

The device as described is alsosupplied with the pegs 21 of any suitable form'in order that they may be pulled out of the ground after havingfserved their purpose.

These pegs 21, Figure 1, are provided in rticulated pre- I vent retrograde movement thereof. 3

The back end of the'casing 1 is provided 13 is similar in construction ward movement a key is "the device by meansofa simple oscillating mposed of two parts: 7

their upper portion with a ridge of semiannular form in order to leave a space 22 in which the lever 15 after removal from its socket or any other similar devicemay-be engaged to rotate the pegs when it is necessary to readily pull them up. These pegs serve to hold the staysv 4 which may be attached in the holes 23 of the casing 1. v V

The apparatus is carried dismounted in the vehicle; when the latter is detained by being stuck in a mud hole, soft clay or sand, in the bed of a stream or in a ditch or cannot go up a grade owing to its steepness, the apparatusis mounted (in front or in the rear of the vehicle at a convenient distance from same) on the tripod, the spikes 11 of the legs resta ing on the surface of the ground. The pegs 21 are introduced in the ground and the stays i at are placed in position without exerting too much stress. The lever 15 is fixed into its socket and the cable 3 is unwound from the drum 7 until it can be fastened to the vehicle by means of the hook 6.

The lever 15 owing to the oscillating move- I ment given to it operates thepinion 12 which in turn willoperate the gear and drum 7 on which the cable 3 is wound. WVhilst the cable 3 is wound on the drum, two opposite forces are created on the cable 8, one from the apparatus to the vehicle and the other from the latter to the former. r

By means of this system, when the cables 3 and 4 are stretched andrthe pegs 11 of the legs 10 have entered the ground the apparatus is firmly anchored to the ground and rests on three points hauling the vehicle towards it, which is exactly what is required.

1 Having thus described my invention and the way in which same is to be worked, what I claim as new and wish to protect by Letters Patent is A supporting frame for a windinginecha- I nism to pull vehicles from swampy ground comprising a casting supporting the winding mechanism, said casting being formed with sockets, legs having their upper ends secured in said sockets, spikes secured to the lower ends of the legs and positioned at an angle thereto, concave discs securing the spikes to the legs and havlng a surface adapted to rest on the surface of the ground, a peg adapted to b'edriven into theground at a 1 A suitable distance from said spikes, and a stay connecting said peg to said casting, said peg and spike being relatively so arranged as to overcome the resistance of the vehlcle.

In testimony whereof, I aflirm my signa- 7 ture.

RAUL LAVANDEIRA;
